Embodiment Construction

[0028] Gravel Aggregate Preparation:

[0029] Break the mined granite, diabase and basalt rocks separately, and sieve out gravels with a particle size of 1-10mm. Then, according to the volume ratio, select 50 parts of granite gravel, 30 parts of basalt gravel, and 20 parts of diabase gravel , mixed into a mixed aggregate.

[0030] Grading:

[0031] According to the volume ratio, the mixed aggregate with a particle size of 1-3 accounts for 20%, the mixed aggregate with a particle size of 3-5 accounts for 30%, the mixed aggregate with a particle size of 5-8 accounts for 30%, and the mixed aggregate with a particle size of 8-10 20%.

[0032] Mixed cement preparation:

[0033] Choose No. 525 portland cement and aluminate cement for blending, and the blending ratio is 80 parts of portland cement and 20 parts of aluminate cement by volume.

[0034] Mixed cement slurry:

[0035] Add water to the mixed cement, and at the same time add 5% water reducing agent, 3% early strength ag...

Abstract

The invention provides a manufacturing method of cement pipe pile for construction, comprising processes of gravel aggregate preparation, blended cement preparation, blended cement pulping, pipe pile casting machine manufacturing, pipe pile mould manufacturing, framework preparation of steel reinforcement, pipe pile shape design and pipe pile manufacturing. The prepared cement pipe pile comprisesa concave arch and a pile rib. The cement pipe pile of the invention has high density and high strength, saving material and energy, suitable for production of foundation pressing type cement pipe pile for construction.

Description

technical field [0001] The invention proposes a method for manufacturing high-strength cement pipe piles for construction in the field of building materials. Background technique [0002] At present, the cement pipe piles used in the construction of building foundations are made by pouring Portland cement in a mold with a steel skeleton, forming and solidifying. In order to increase the density, the centrifugal casting method is usually used. In order to increase the strength, usually Steam-cured kiln steam-cured. Because the steel frame is made of binding, the cement is made of ordinary Portland cement, and the gravel is made of river sand and mountain stone slag, so there are many voids, low density, low bonding degree between steel bars and concrete, and low relative strength. Contents of the invention [0003] In order to realize high-strength pipe piles, the invention proposes a method for manufacturing high-strength cement pipe piles for construction. The method so...
